What is the average life span of koi fish? -Leon

Most Koi live about 20-30 years. That is usually cut short due to an accident or a miss hap. There's a joke about how a Koi will live until the owner kills it. It is not uncommon to find a 30-60 year old Koi in some ponds around Asia.

The oldest Koi ever recorded was named Hanoko. Apparently, it lived to be about 226 years old and was kept in a natural pond in someones backyard in Japan. Hanoko was passed on down from generation to generation and even lived through many earthquakes. Hanoko was not a very pretty Koi, it was kept as a pet when the whole "selective breeding" thing just started, it was only a dull red color. Hanoko died back in the 1970's. The owners had the rings in its scales counted, like the tree rings in a tree trunk, to determine its age.
